Tyana Cozette Cavanagh

My babies loves Dr. L! My two year old looks forward to seeing him every time we have to make a visit and my 1 year hardly ever cries during visits! He’s very professional and takes the time to answer any questions I have. The nurses are always so sweet and patient with my sometimes overwhelmed babies.

Carol Garcia Lopez

It is easy to make appointments. The front desk staff are very helpful. The physicians are very thorough and knowledgeable. I will continue to bring my children here because I trust their professionalism.


Rayala is caring, funny when its OK to be & serious when he needs to be. He's a great person & doctor. I didn't know my sons true personality until they helped him. My son would scream/cry during BMs, he was clingy, we both were a mess. He still has obstacles to overcome, but I feel confident

Virginia Calvillo

Polite doctor, very thorough with explanations & tries to answer every question you may have or address any concerns. Goes over questionnaire about child’s progress. Patient with the kids.


My teenage son (16 y.o) went in recently for his Annual Physical at A thru Z Pediatrics. He was seen by Dr Rayala who has this unique way of getting a teenagers attention. He was very thorough for the most part and with a calm voice very frank about things of concern. Like good eating habits,
